Multi Band WDM Filters

Why use multi-band pass filters?

Traditionally, single band pass filters have been used in telecommunication modules to perform wavelength/channel add-drop functionality and are commonly used components in WDM system and PON modules.

Iridian has previously developed CWDM and wide band multi-band pass filters to reduce accumulated insertion loss in these module/systems by “grouping” of ITU channels/wavelengths.

With this method, module and system designers can improve the performance of these optical modules by using fewer components, resulting in a reduction in insertion loss and a more compact module size.
